Are Diamonds Really Formed from Coal?

Diamonds have long captivated our hearts, symbolizing enduring love and elegance. A common myth suggests that these precious gems originate from coal, undergoing transformation under immense pressure and heat deep within the Earth. However, this popular narrative doesn't align with geological realities.

In truth, diamonds form in the Earth's mantle, approximately 90 to 125 miles beneath the surface, where temperatures soar and pressures are immense. Here, carbon atoms crystallize over millions, or even billions, of years to create diamonds. In contrast, coal forms from the compressed remains of ancient plant material, typically found much closer to the Earth's surface, within 2 to 3 miles deep. This significant difference in formation depth and origin means that coal is unlikely to be the source of diamonds.

Moreover, most diamonds are far older than Earth's first land plants—the source material for coal. This age discrepancy further debunks the idea that diamonds originate from coal. Instead, diamonds are brought to the Earth's surface through volcanic eruptions, encased in a type of igneous rock known as kimberlite.
